One-year old sea trout and land-locked brown trout were stressed from the end of July until mid-November by draining the water completely from the tank for 3 min from 1 to 4 times/week. Smolting status was estimated by monitoring individual migration

In an experimental flume tank, two-year-old, 20 cm Salmo trutta from both anadromous and freshwater resident stocks showed increased downstream movement, mostly diurnally, as the water temperature rose, from early May to early June, most intensely fr
